Nice laser you got there! I really wanted to keep that one when I finished it. I don't know the actual wavelength of the laser but compared to my other 445nm lasers it was noticeably more blue. It certainly appears to be a higher wavelength.

The diode is a M140 from DTR and he said it was a high efficiency one. He did not state that it was a higher wavelength. That was my observation.

Yes this diode came from the projector that was from the M140 thread that was binned to see if they were more efficient than the A140's. It was not tested for wavelength but RHD did some wavelength tests and he came out with about an average of 450nm if I remember correctly which was a little higher than the average A140.
